Processes a) through u) also form part of the invention.

The starting materials of formula II or III are either known or may be prepared analogously to known methods.

The compounds of formula I have herbicidal activity as observed after their pre-emergent or post-emergent application to weeds or a weed locus.

The term "herbicide" (or "herbicidal") refers to an active ingredient (or an effect) which modifies the growth of plants because of plant growth regulating or phytotoxic properties so as to retard the growth of the plant or damage the plant sufficiently to kill it.

Application of a compound of formula I is made according to conventional procedure to the weeds or their locus using a herbicidally effective amount of the compound, usually from 10 g to 10 kg/ha.

Compounds according to the invention may be used in the control of both broad-leaf and grassy weeds on both pre- and post-emergent application. Compounds may also exhibit selectivity in various crops and are thus suited for use in weed control in crops such as corn, cotton, wheat, soybean and rice.

The optimum usage of a compound of formula I is readily determined by one of ordinary skill in the art using routine testing such as greenhouse testing and small plot testing. It will depend on the compound employed, the desired effect (a phytotoxic effect requiring a higher rate than a plant growth regulating effect), the conditions of treatment and the like. In general satisfactory phytotoxic effects are obtained when the compound of formula I is applied at a rate in the range of from 0.01 to 5.0 kg, more preferably of from 0.05 to 2.5 kg per hectare, eg 0.05 to 5.0 kg per hectare, especially 0.1 to 2.5 kg per hectare.

The compounds of formula I may be advantageously combined with other herbicides for broad spectrum weed control. Examples of herbicides which can be combined with a compound of the present invention include those selected from the carbamates, thiocarbamates, chloroacetamides, dinitroanilines, benzoic acids, glycerol ethers, pyridazinones, semicarbazones, uracils and ureas for controlling a broad spectrum of weeds.

The compounds of formula I are conveniently employed as herbicidal compositions in association with agriculturally acceptable diluents. Such compositions also form part of the present invention. They may contain, aside from a compound of formula I as active agent, other active agents, such as herbicides or compounds having antidotal, fungicidal, insecticidal or insect attractant activity. They may Be employed in either solid or liquid forms eg in the form of a wettable powder or an emulsifiable concentrate incorporating conventional diluents. Such compositions may be produced in conventional manner, eg by mixing the active ingredient with a diluent and optionally other formulating ingredients such as surfactants.

Agriculturally acceptable additives may be employed in herbicidal compositions to improve the performance of the active ingredient and to reduce foaming, caking and corrosion, for example.

The term "diluent" as used herein means any liquid or solid agriculturally acceptable material which may be added to the active constituent to bring it in an easier or improved applicable form, respectively, to a usable or desirable strength of activity. It can for example be talc, kaolin, diatomaceous earth, xylene or water.

"Surfactant" as used herein means an agriculturally acceptable material which imparts emulsifiability, spreading, wetting, dispersibility or other surface-modifying properties. Examples of surfactants are sodium lignin sulfonate and lauryl sulfate.

Particularly formulations to be applied in spraying forms such as water dispersible concentrates or wettable powders may contain surfactants such as wetting and dispersing agents, for example the condensation product of formaldehyde with naphthylene sulphonate, an ethoxylated alkylphenol and an ethoxylated fatty alcohol.

In general, the formulations include from 0.01 to 90% by weight of active agent and from 0 to 20% by weight of agriculturally acceptable surfactant, the active agent consisting either of at least one compound of formula I or mixtures thereof with other active agents. Concentrate forms of compositions generally contain between about 2 and 90%, preferably between about 5 and 70% by weight of active agent. Application forms of formulation may for example contain from 0.01 to 20% by weight of active agent.

Typical herbicidal compositions, according to this invention, are illustrated by the following Examples A, B and C in which the quantities are in parts by weight.

EXAMPLE A

Preparation of a Dust

10 Parts of a compound according to this invention and 90 parts of powdered talc are mixed in a mechanical grinder-blender and are ground until a homogeneous, free-flowing dust of the desired particle size is obtained. This dust is suitable for direct application to the site of the weed infestation.

EXAMPLE B

Preparation of a Wettable Powder

25 Parts of a compound according to this invention are mixed and milled with 25 parts of synthetic fine silica, 2 parts of sodium lauryl sulphate, 3 parts of sodium ligninsulphonate and 45 parts of finely divided kaolin until the mean particle size is about 5 micron. The resulting wettable powder is diluted with water before use to a spray liquor with the desired concentration.

EXAMPLE C

Preparation of Emulsifiable Concentrate (EC)

13.37 Parts of a compound according to this invention are mixed in a beaker with 1.43 parts of Toximul 360A (a mixture of anionic and non-ionic surfactants containing largely anionic surfactants), 5.61 parts of Toximul 360A (a mixture of anionic and non-ionic surfactants containing largely non-ionic surfactants), 23.79 parts of dimethylformamide and 55.8 parts of Tenneco 500-100 (predominantly a mixture of alkylated aromatics such as xylene and ethylbenzene) until solution is effected. The resulting EC is diluted with water for use.

The following examples are provided to illustrate the practice of the present invention. Temperature is given in degrees Celsius. Abbreviations used in this specification.

EXAMPLE 1 7- chloro-3-(4,6- dimethoxy-2-pyrimidinyl)phthalide (Table A, cpd. no. 6)

1.68 g (0.0 mol) of 7-chlorophthalide is added to 100 ml of dry THF and the mixture cooled to -70° C. 6.8 ml (0.01 mol) of 1.5M LDA is then added over 3 minutes and the reaction mixture stirred at -70° C. for 15 minutes. 2.18 g (0.01 mol) of 2-methylsulfonyl-4,6-dimethoxypyrimidine in 50 ml of THF is then added and the mixture stirred for 4 hrs with temperature being maintained at -75° to -70° C. The reaction mixture is neutralized with 1.5 g of NH₄ Cl in 5 ml of water, warmed and concentrated on a rotovaporator. The concentrate is partitioned between CH₂ Cl₂ /H₂ O (50 ml each) and the aqueous phase separated and treated with further 30 ml of CH₂ Cl₂. The combined CH₂ Cl₂ phases are washed with 30 ml of water, separated and concentrated. The concentrate was flash chromatographed on silica gel using 80/20 hexane/ethyl acetate (500 ml), 50/50 hexane/ethyl acetate (500 ml) and 80/20 acetone/methanol (500 ml) (30 fractions×50 ml). The title compound (fractions 9-23) was obtained after recrystallization from hexane/CH₂ Cl₂ as a white solid, m.p. 148°-149° C.

EXAMPLE 2 5-(4,6-dimethoxy-2-pyrimidinyl)-furo[3,4-b]pyridine-7(5H)-one (Table B, cpd. no. 40)

A solution of 1.3 g (0.0096 mols) of furo [3,4-b]pyridine-7(5H)-one in 50 ml of dry THF is cooled to -75° C. and 8 ml (0.0192 mols) of 2.5M LDA added dropwise over 5 minutes. The mixture is allowed to react for 1 hr at -750° C. and 2.1 g (0.0096 mol) of 2-methylsulfonyl-4,6-dimethoxypyrimidine in 30 ml of dry THF added dropwise over 10 minutes. The mixture is allowed to warm to RT, 1.6 ml of HCl added and the THF evaporated off. The residue is dissolved in 75 ml of CH₂ Cl₂, washed with water (2×50 ml) and the organic phase concentrated to give a yellowish white gummy solid. This is chromatographed on a silica gel column using 50/50 hexane/ethyl acetate (500 ml), ethyl acetate (500 ml) and 80/20 acetone/methanol (1000 ml) (30 fractions). The crystalline residue (fractions 18-21) of the title product has m.p. of 167°-168° C.

EXAMPLE 3 7- chloro-3-methoxy-3-(4,6-dimethoxy-2-pyrimidinyl)-2-methyl-isoindol-1(3H)-one (Table C, cpd. no. 54)

The reaction mixture is then washed with saturated brine solution (3×50 ml) passed through phase separating paper and the filtrate concentrated. The concentrate is dissolved in methylene dichloride, charcoal treated at RT for 1 hr and filtered.

The filtrate is concentrated to 60 ml diluted with hexane, digested for 1 hr at 35° and allowed to crystallize overnight at RT. The precipitate is filtered to isolate 35.15 g of the title product m.p. 124°-126° C.
